I wanted to bump this because I think I am having the same problem...
2000 HP500EFI
Runs for a bit then dies.. ... wait a few and starts for a few seconds and dies again. This just happened today . Ran just long enough to get it off the trailer and then died while docking.... Grrrrrr.... missed the poker run and the only nice boating day we've had for a month!
I replaced the water seperator but did not prime it.... .. does it HAVE to be primed? After that it started up and ran for a minute then died... checked the seperator for fuel and it was dry ...
I can hear the fuel pump buzz when I turn the key on ... I did this many times to try and prime the system ... finally got it to start again but it died ... this time the seperator was about 1/2 to 3/4 full of fuel..
So... think this is still a priming problem or is it a fuel pump issue?
Also.. should I change the filter just before the fuel rail on the back of the engine?
Thanks!
